Patent CA-2475669-A1 (CA)
Title: Digital stamp
Inventor: SILVERBROOK KIA
IPC: B41K1/00
Filed: 2003-02-12
Abstract: A digital stamp is described which can print out a message using a moveable inkjet printhead (30) which can be moved by a mechanical arrangement of arm (35) and pivots (33, 36). A cartridge (20) containing ink feeds the printhead (30) with monochrome or color ink via lines (52). Movement of the upper section (10) of the housing towards the lower section (12) of the housing moves the arm (35) to slide the printhead (30) across the aperture (34) in the lower section (12) while at the same time electronic signals fed to the printhead (30) print out the stored message. A spring (42) returns the printhead (30) to its inoperative position once having traversed the opening (34). The stored message may be fixed, replaceable or programmable or may be one from a fixed number of stored or updateable messages or images or can be input by an attached apparatus, for example, a CCD imager, to record an image and to print it via the printhead (30). The digital stamp can replace a rubber stamp in an office or may be used to print labels in a retail environment. An infra-red ink may also be supplied which can be used to print an encoded digital message with or on top of a visual print-out as a security measure when a printhead having the necessary number of inkjet nozzles is employed.

Title: Equalization of multiple signals received for soft handoff in wireless communication systems
Inventor: FERNANDEZ-CORBATON IVAN JESUS
IPC: H04B7/02
Filed: 2004-02-23
Abstract: Techniques for performing equalization of multiple signals received by a terminal in soft handoff with multiple base stations. The received signal at the terminal is conditioned and digitized to provide a stream of received samples (ym), which is then equalized/filtered (410) with multiple sets of coefficients to provide multiple streams of transmit chip estimates (Xk). One set of coefficients (fk) is provided for each base station and is used to provide a corresponding stream of transmit chip estimates. The multiple streams of transmit chip estimates are further processed (420) to provide multiple streams of data symbol estimates (dk), one stream of data symbol estimates for each base station. The multiple streams of data symbol estimates are then scaled (430) with multiple scaling factors (.alpha.k) and combined (432) to provide a stream of combined data symbol estimates (dk). The processing for the multiple base stations may be performed by a single hardware unit in a time division multiplexed manner.

Title: A method and kit for detecting the early onset of renal tubular cell injury
Inventor: DEVARAJAN PRASED
IPC: A61K31/675
Filed: 2004-03-26
Abstract: A method and kit for detecting the early onset of renal tubular cell injury, utilizing NGAL as an early urinary biomarker. NGAL is a small secreted polypeptide that is protease resistant and consequently readily detected in the urine following renal tubule cell injury. NGAL protein expression is detected predominantly in proximal tubule cells, in a punctate cytoplasmic distribution reminiscent of a secreted protein. The appearance NGAL in the urine is related to the dose and duration of renal ischemia and nephrotoxemia, and is diagnostic of renal tubule cell injury and renal failure. NGAL  detection is also a useful marker for monitoring the nephrotoxic side effects of drugs or other therapeutic agents.
